OCCUPATION On the whole, the occupational grouping is based on the nomenclature of the Standard Classification System of Occupations (FEOR) modified in 1984. With regard to the major groups of occupations, there is a difference only in the case of the major group "Agricultural manual occupations" which — contrary to the FEOR — includes alsó agricultural unskilled workers and agricultural day-labourers, who are taken out of the major group "Other manual occupations". In the chapter "Comprehensive data", the tables by major groups of occupations are supplied with notes to this effect but the data of the major group "agricultural occupations" in the further chapters include alsó agricultural unskilled workers. In the occupational groups, the occupations "physicians" and "pharmacists" were united. The type of activity is the basic grouping of occupations, scopes of work which differentiates between the — manual and the — non-manual activities. The major groups of occupations are groups förmed within the manual and, respectively, non-manual activities, in which the manual and the non-manual occupations are together or separated, primarily by their industrial character and, respectively, by the so-called type of work. Major groups of manual occupations are the following: Mining and manufacturing-related Construction-related Agricultural Transport, post and telecommunication-related Trade and hostelry-related Water works and supply, health and services-related Material conveyer operators, freight handlers Other manual occupations The major groups of non-manual occupations are the following: Technical Public administration, jurisdiction, economy, transport and trade-related Health and culture-related Accounting, banking-related, financial and other non-manual Individual occupation is the regular activity pursued by the active earner at the census moment which is his/her main source of livelihood. Persons were included in one of the groups, then major groups of individual occupations by the character of their declared occupation, in generál independently of their educational attainment, position in work or employer. 261
